Body Count (Original Cut): 854. The film is 94 minutes long, so it has 9.085 kills per minute.
The film took three years to make and has over 2,000 shots. Act 3 has almost a third of the shots in the entire film.
Except for a few digitally-created effects like sparks and lightning, all elements (characters, backgrounds, weapons, etc) were hand-drawn, scanned, colored digitally in Photoshop CS4 and then animated in After FX CS4.
Takes place after the Infinite Santa 8000 Web Series.
For the web series, although the elements were 2d, they were set up in a 3D space. This allowed the digital lights to behave more like actual lights (casting shadows, etc). However, this was very time-intensive, so for the movie they lit each element separately, which was much faster.
